Application filed March 20,1816. Serial No. 85,437.

To all whom it may concern:

citizen of the United States, residing at Hagerstown, in the county of \Vashington and State of Maryland, have invented a newand useful Furnace, of which the following is a specification.

,The present invention appertains to furnaces, and aims to provide a novel and improved one register or .pipeless hot air furnace for use in dwellings, churches, school houses, and the like.

it is the object of the invention to provide a, one registerhot air heating furnace pro vided with novel means for thecirculation of the' cold and heated air, to enhance the efiiciency of the furnace.

- It is also within the scope of the'invention to rovide a hot air furnace of the nature indicated, which is of extremely simple construction, which can be readily manufactured and set np,.and which will be satisfactor and efficient in use.

' proceeds,

ith the foregoing and other objects in view which will appear as the description the invention resides in the combination' and arrangement of parts and in thedetails of construction hereinafter dethe invention 'Within' the scope of what is claimed without V 1 Fig. line 2--2 of Fig. 1, portions being shown in line-M of Fig. 2.

"scrlbed and claimed, it being understood that changes in the precise embodiment of herein disclosed can be made do arting from the spirit of the invention. e invention is illustrated in the accompan g drawings, where1n:-

Figure 1 is a plan view of the furnace.

2 is a vertical section taken on the elevation; v

Fig. 3 is a horizontal section taken on the Fig/l is an elevation of the furnace, portions being broken away and shown in sectijon.

The furnace includes a fire pot 1 and radiator? and accompanying parts, providing. a heating plant which is lnclosed bya sheet metal jacket or casing 3 provided ings 6 extending to the.

Sheet metal channels 7 have their flanges or edges secured in any suitable manner to the walls of the jacket 3 so that their lower ends communicate with the openings '4, and the upper ends of said channels communicate with the openings 6., The upper ends of the channels 7 are inclined, as at 8, to extend to the side walls of the box 5 having the open ings 6. The channels? are upon opposite sides of the jacket 3, and conduct the cold air downwardly along the opposite sides of the jacket to the lower end of the jacket. The upper end of the channel 7 being united with the box ,5 provides an arch-like structure straddling the jacket 3 with'the lower edge of thebox 5seated u on the upper end of, the jacket andwith t e inwardly projecting flanges of the channels resting against and secured to opposite sides of the jacket. This provides for the efleetive' agplication of the present improvement to t furnace proper, and it will be noted that fresh airin pawing down the channels ill come in contact with the jacket 3 to be heat ed thereby even before enteringihe jacket through the openings 4.

A plurality, in this case five, short vertical pipes 9 are disposed within the box 5 in the arrangement illustrated in Figs. 1 and 3, and the lower ends of said pipes are attached to the upper end of the acket 3 for conducting-the heated airupwardly. The pipes 9 are spaced apart to provide cold air passages within the box 5.

The register, only one being used, embodies a floor plate 10 fitted in the floor 11 of the building, and having a plurality of depending annular which at t e same time has an excellent heating effi iency. The cold air is drawn from the room or chamber which is heated, the same passing downwardly through the register into the register box 5 between the pipes 9, and the cold air passes from said ox downwardly through the cold air Chan, nels 7 and thence through the openings,

into the lower portion of the jacket 3. It will be noted that the cold air in passing around the pipes 9 and along the jacket 3 will receive its initial heat, and after the air is finally heated within the jacket 3 it passes upwardly through the pipes 9 into the room in a plurality of streams or currents. The hot air thus rises through the pipes 9 while the cold air passes .lownwardly around said pipes. By providing the plurality of pipes S), the circulation of air is increased, and the radiating surface between the pipes 9 and cold air within the box 5 is also incr ased. The register can be used below one or more partitions, whereby the several pipes 9 supply the heated air into a plurality of rooms, the. cold air being drawn off sii'nultaneously through the single register.

As a means for humidil'ying the air, for the comfort of the occupants, and to avoid the cracking of furniture, and the like, the back of one channel 7 is provided with a horizontal slot 14, and an inclined plate has its upper edge portion secured to the channel 7 by means of an angle member 16, said plate 15 projecting within the channel and sloping from said slot 14. A. water receptacle or reservoir 17 is supported upon the outer side of said channel by means of brackets'lS attached thereto, and an arched frame 19 is attached to the ends of said receptacle adjacent the channel 7. A horizontal shaft 20 is journalcd through the limbs of the frame 19 and has secured thereon between its ends a. copper roller 21. and a second horizontal shaft 22 above the shaft 20 extends through vertical slots 23 provided in the limbs of the frame 1!), and a zinc roller 24 is mounted upon the shaft 22 between its ends and above the copper roller 21. One end of the shaft 22 is provided' with a crank 25 for rotating the roller 24. The shaft is engaged through the downturned ends of a yoke 26 slidablc vertically within the frame 19, and an adjusting screw 27 is threaded through the central portion of the frame 19 and bears downwardly upon the yoke 26. The screw 27 enables the yoke 26 to he forced downwardly to bring .the roller 24 nearer the roller 21. A flat wick 2 8 ofsuitable absorbent material is passed between the rollers 21 and .24 with its outer terminal dipping in the water within the re,- cept-acle 17. The wick 28 passes through the slot 14 and rests upon the plate 15, being supported by said plate within t-hc channel in a pendent position, as seen in Fig. 2.

The water will be absorbed by the wick and raised by capillary attraction from the receptacle 17 between the rollers 2124 and thence over the plate 15 to the depending and to collect the dust from the air.

portion of the wick within the cold air channel. llloisture is thus supplied to the air to humidity it. The roller 21 can be rotated for adjusting the wick, and the screw 27 can be adjusted to regulate the pressure upon the wick between the rollers, whereby to regulate the amount of moisture which is permitted to pass between the rollers into the cold air channel. It is thus possible to adjust the wick and to adjust the pressure roller 24, in order that the amount OflllOlSiilllG supplied to the aircan be controlled to a nicety.

.O'ne side of the channel 7 which has the hun'iidifying means is provided with-a glass window 29, through which the lower end. ofi wick 28 can be seen, to note the condition thereof. Said side of the channel is provided below the window 29, with an opening 30 normally closed by a vertically sliding door 2-H movable in guides 32 attached to the channel, whereby access may be had into the lower portion of the channel. A tray 33 is slidable through the side of the channel T below the door 51 and is normally disposed below the wick 281:0 catch the drippings, a. felt or other suitable pad 31 being disposed within the tray 33 to' absorb the drippings, The tray 33 can be drawn out of the channel for cleaning it.

Having thus described the invention, what is claimed as new is: j

A furnace embodying a jacket having 0pposite lower inlet openings, a register box above the upper end of the jacket and having openings in its opposite sides extending to the lower edges thereof, opposite vertical channels having their upper ends attached to said sides of said box around'the openings .100 thereof and having their llangcs projecting inwardly, said channels and box providing an archlil e structure straddling the jacket with the loweredgc of the box seating upon the" upper end of the jacket and the edges of the channelllanges secured to opposite sides ofsaid jacket whereby air flowing through said channels' comes in contact with the jacket, the lower ends of the channels communicating with said inlet openings of the 1 10 jacket, a hot air pipe rising from the upper end of the jacket within said box and a register fitted upon said box and the upper end of said pipe. y

In testimony that I claim the l'oregoi'ig .15 as my own, I have hereto allixcd my sigrlature in the presence of two witnesses. i
